竹黄菌液体培养条件下生成竹红菌素的研究

Study on Fermentation Hypocrellin Pigments by Shiraia Bambusicola Henn under Liquid Condition

研究了竹黄菌液体培养生成竹红菌素过程中培养条件的影响。结果表明竹黄菌生长及竹红菌素生成适宜的温度、pH值分别为26℃、5.5～6.0,并且整个过程需要充分的溶氧。液体培养的最适碳源为葡萄糖,浓度为30g/L。最适氮源为土豆汁,浓度为20%。

The culture of hypocrellin pigments under liquid condition by Shiraia Bambusicola Henn was studied. The suitable temperature and initial pH is 26℃ and 5.5～6. The dissolved oxygen should be abundant. The optimum carbon source is glucose which concentration is 30 g/L. The optimum nitrogen source is potato extract which concentration is 20%.
